The stainless steel planchette from alpha-spectroscopy analysis is washed with a hydrofluoric/nitric acid solution to remove the plutonium. The plutonium solution is passed through an anion exchange column and the plutonium is eluted from the column by addition of a hydrochloric/hydroiodic acid solution. The sample is evaporated to dryness and re-dissolved in a hydrochloric acid/peroxide solution The sample is loaded on a second anion exchange column and plutonium is eluted from the anion exchange column with hydrobromic acid, into a pre-cleaned quartz test tube. Approximately 1,500 samples per year are processed for TIMS analysis.
